'Sprinkling' in the Bible

For if the blood of goats and bulls, and the ashes of a heifer sprinkling those who have been defiled, sanctify to the cleanness of the flesh:

By faith, he kept the Passover, and the sprinkling of the blood, that the destroyer of the firstborn should not touch them.

to Jesus, the mediator of a new covenant, and to the blood of sprinkling that speaks better than that of Abel.
